Highres GP4

Is there anywhere i can find all the original GP4 tracks in highres textures. So there are no blurry ones? thanks!

In my GP4 I didn't have blurry textures on the tracks. Why don't you modify your graphic card settings?
Several track updates have been released, though. I don't think you'll find the original tracks updated, but some modifications which make them more enjoyable, and in some cases even totally new tracks, such as Bahrain, Hockeneim 2006, some fantasy tracks, all of a high quality!

you should enable anistropic filtering to prevent blurry tracks.
